Facebook Working on Ad Network, Focused on App Install Ads

We all called this from the get go and FB is just doubling down on what works:

That’s because app install ads — the kind that get you to download Candy Crush Saga or Jack Threads or whatever to your phone — are booming, a fact that Facebook has acknowledged without spelling out exactly how big that business has become. But I’m reasonably certain that app install ads — an ad market that barely existed a couple years ago — now account for a very substantial portion of Facebook’s mobile ad revenue, which now accounts for half of Facebook’s ad revenue.
